During construction
When handling adhesives and solvent-based materials it is important to observe the
safety notes and instructions supplied by the manufacturer. Many glues and solvents
are capable of causing injury and damage to materials if they are not used com-
petently. Take waste glue and paint to your local model shop or toxic waste collection
centre.
Note that balsa knives, pins, etc. have sharp points and edges, and should be hand-
led carefully to avoid injury.
Take care to keep tools, adhesives and paints out of the reach of children.
A large, unobstructed working surface is a great advantage for all types of model-
making.
If you are a relative beginner and are not sure of any process, ask an ex-
perienced modeller for help.

Areas of the fuselage which are to be glued should be rubbed down with fine-grit
abrasive paper to remove any lingering traces of mould release agent. Carefully re-
move all sanding dust. Aim at reducing the glossy surface to a
matt
finish, otherwise
there is no chance of a durable glued joint between the fuselage and other parts.
When using adhesives it is important to observe the instructions supplied by the glue
manufacturer. The main Graupner FS catalogue includes many other types of ad-
hesive.
When you are using solvent-based adhesives be sure to provide good ventilation in
your workroom.
Read the manufacturer’s instructions.
